Rear differential6
The open rear differential converts the angle of drive
through 90° and distributes drive, via the rear drive
halfshafts, to the rear wheels.

Lesson 2 – ChassisRear Drive Axle and Differential 

The open rear differential for the V6 and V8 petrol
variants has the same output ratio, but the output ratios
for the TdV6 diesel are different, depending on whether
automatic or manual transmission is fitted.
The open rear differential is located centrally in the rear
of the chassis.
The units are mounted to the chassis via rubber bushes
and bolts; two mounting points at the rear of the unit
and one at the front.

Planet...

The differential comprises a pinion shaft and hypoid
pinion gear and a crown wheel drive gear with an
integral cage, which houses two planet gears. Two sun
wheels are also located in the cage and pass the
rotational drive to the drive shafts.
The pinion shaft is mounted on two opposed taper roller
bearings, with a collapsable spacer located between
them. The spacer is used to hold the bearings in
alignment and also collapses under the pressure applied
to the pinion flanged nut. This allows the flanged...

SERVICE
The oil used in the open rear differential is Castrol
SAF-XO. The oil contains unique additives, which
enhance the differentials operation. No other oil must
be used in the open rear differential.

Differential3
The electronic rear differential locking and biasing
feature is actuated via a DC motor, which is controlled
by the electronic rear differential control module, via a
Pulse Width Modulation (PWM) signal.
